Tomato planting management technical points

Planting tomatoes is a good way for farmers to become rich, and strengthening the management of the growth period of tomatoes is the key to obtaining high yield and high efficiency.

1. Grasp the management of growth period. Including cultivating weeds, water conservation, arranging vines, pruning branches, removing old leaves, ventilation, lightening, prevention and control of pests and diseases, strengthening of temperature management and other measures. Among them, diseases of tomatoes mainly include viral diseases, bacterial wilt, early blight, and late blight; insect pests mainly include cotton bollworm and aphids. Diseases of tomatoes can be prevented and intractable, and should be based on "defense." Virus disease prevention methods include: selection of disease-resistant varieties, seed disinfection, seedling depression, control of aphids, appropriate early planting and so on. The temperature management is to appropriately increase the ventilation of the greenhouse during the day so that the temperature inside the greenhouse can be maintained at about 25°C. The night temperature is maintained between 10-13 °C. When starting to vent, the air outlet should be small to large, ranging from small to large. After the temperature decreases in the afternoon, the air outlet will be gradually reduced or closed.

2. Do a good job of fertilizer and water management. The growth period of tomatoes generally does not require watering during the summer and autumn rainy seasons, but when the 2nd to 3rd fruits are ripe when they are dry, they should be properly watered. According to the growth of tomato plants, timely topdressing to promote fruit development, flower protection and fruit preservation. Fertilizer than tomato tomatoes, their fruit surface color sweetness output are higher than a few grades, generally as a base fertilizer can be applied to the golden baby microbial fertilizer, top dressing can be applied to the gold seedling root strong or seedling strong, if spraying gold Baby sweetening spirit will make it look better. If the deficiency of the individual greenhouses is more serious, it can be used to spray Jinbao supplements to boost the spirit (promote the growth-promoting spirit), which has a special effect.

3. Pick fruit timely. Ripe tomatoes have matured, discolored, matured, and matured for four periods. Storage and preservation can be harvested during the green season. The transport can be harvested during the discoloration period (1/3 of the fruit turns red). Local sale or self-feeding should be harvested when ripe fruit is more than 1/3 red. Harvesting should be carried out gently and lightly. Picking is best done without a fruit pedicle to prevent the fruits in the shipment from being stabbed each other. It is not advisable to use hormones to stimulate fruit coloring during fruit ripening period. Its advantage lies in reducing the production cost, improving the quality of the fruit, and safeguarding the food safety of consumers.

Laser Distance Meter

Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.

Trade your heavy tape measure for laser rangefinder, which let you simply take measurements with one hand. No matter your job, the laser rangefinder will help you measure much farther, with greater accuracy and in more situations, saving you money and time.
